Commonwealth expert scientific committee slams Arrow CSG project

A Federal Government independent panel has slammed a multi-billion dollar coal seam gas proposal in Queensland.

The Independent Scientific Expert Committee (IESC), set up by the Federal Government to advise on the water impacts of resource projects, has delivered a stinging critique of the Arrow coal seam gas project in Queensland.

Arrow is owned jointly by Shell and PetroChina.

Some of the key conclusions reached by the Committee in its advice on the draft Arrow Environmental Impact Statement (EIS) were that:

  • .."the draft  Environmental Impact Statement does not adequately address potential impacts to Matters of National Environmental Significance"
  • "The Committee considers that Matters of National Environmental Significance are likely to be impacted by drawdown associated with cumulative impacts caused by this and other projects"
  • "The Committee does not consider that the modelling undertaken is adequate and includes a number of limitations...... This raises concerns about the robustness of the drawdown predictions made using the numerical model."
  • "The Committee considers that the proponent has not adequately developed a site and regional water balance that allows an assessment of cumulative impacts."
  • "The Committee considers that well failure during construction, operation and decommissioning phases of the project has the potential to cause aquifer inter-connectivity....The Committee considers that a risk assessment of well integrity is required to enable potential impacts at a regional scale to be adequately determined.
  • "The Committee considers that further information is required to make an adequate assessment of potential impacts from brine disposal, including storage locations, water quantities and water qualities.  Further, eco-toxicity tests are required to support proposal disposal options".

President of the Lock the Gate Alliance, Drew Hutton, said the Committee's advice had delivered the draft Arrow EIS an unequivocal "fail" mark.

"The IESC report is nothing short of a damning critique of the draft EIS, raising numerous concerns about impacts on groundwater, including  potential draw downs in the Condamine Alluvium aquifer that irrigates the central Darling Downs region," Mr Hutton said.

"This report basically exposes failures on every front - well integrity, disposal of produced salt and waste water, groundwater modelling, surface water and groundwater connectivity modelling, and impacts on nationally protected matters.

"These issues are fundamental to any project of this size and the fact that the best water experts in the country have given such a damning critique suggests that Arrow should be required to go back to the drawing board and start again.

"We're asking for the process to be suspended and for Arrow to be required to go back to the drawing board and meet the requirements of the IESC. They should not be allowed to proceed to the Supplementary EIS stage with this cloud hanging over their project.

"Federal Environment Minister, Tony Burke, must show some nous and reject this proposal.

"In the meantime the farming community at Cecil Plains and elsewhere across the tenement will continue to lock their gates on Arrow. This will be a major problem for the company because the Cecil Plains area contains at least a third of the gas being sought.

Plibersek must act as NT Gov approves Tamboran’s latest frack plan

June 07, 2024

Federal Environment Minister Tanya Plibersek must ensure Tamboran’s “Shenandoah South” fracking plan is scrutinised under new water trigger laws, after the NT Government signed off on the project without requiring further assessment. The decision was made at 7pm Thursday in the leadup to the first long...
